WebPKI

WebPKI is a security utility from Lacuna Software that handles digital signatures and public key infrastructure (PKI) operations on macOS. It functions as a system extension or helper application for managing digital certificates, validating signatures on documents and code, and facilitating secure authentication workflows. WebPKI is used primarily by organizations and individuals who need to verify digitally signed documents, validate certificates, or integrate PKI functionality into their workflows. The app operates largely behind the scenes and may be installed as a dependency of other applications that require PKI support.
